Evam... Cātur-varṇyaṁ mayā sṛṣṭam (BG 4.13). The first of all... Unless this division is there, that is animal society. That is not human society if these four divisions are not. Varṇāśramācāravatā puruṣeṇa. Systematic human society means
- varṇāśramācāravatā
- puruṣeṇa paraḥ pumān
- viṣṇur ārādhyate panthā
- nānyat tat-toṣa-kāraṇam
- (CC Madhya 8.58)
This is required, varṇāśrama. That is again confirmed here, evaṁ jñātvā kṛtaṁ karma pūrvair api mumukṣubhiḥ. Mumukṣubhiḥ. The real business is mumukṣā, how to get out of this business of repetition of birth. People do not know it. They do not know what is the aim of life. The aim of life is mumukṣā. This human life is meant for that, to get out of the cycle of birth and death. The animal cannot know this. Therefore it is called mumukṣubhiḥ, "one who wants to get rid of this business of repetition of birth and death." Mumukṣubhiḥ. Kuru karmaiva tasmāt tvam.
